CLEANING AND OILING DEVICE FOR OIL STONES Filed Nov. 4, 1929 WWI/"en Z81 (l/t%ess: Edez6 JZ 3rown Patented Feb. 21, 1933 EDELE J. BROWN, OF CHICAGO, ILLINOIS CLEANING AND OILING DEVICE FOR OIL STONES 7 Application filed November 4, 1929. Serial No. 404,778.

My invention relates to cleaning devices and more particularly 'it relates to devices for oiling and removing fine metallic particles from a cleaning or polishing tool, such as an oil stone or the like. It is well known to those familiar with-the art of sharpening tools ,or of polishing metallic surfaces by abrasion with oil stones and other devices, that the effectiveness of the stone requires its 10 frequent cleaning, as otherwise the metallic particles which are worn away from the members subjected to such sharpening or grinding processes will remain on the surface of the stone. The metallic particles thusmixed with the oil and grit worn from the stone form a mixture which hardens if permitted to remain on the surface of the stone, such mixture acting to prolong the time required for sharpening or polishing and making it .diflicult, if not impossible, to get the desired cutting edge'or polished surface. The finely divided particles of metal not only become mixed with the oil and grit, but tend to fill the pores or the interstices that exist in the 5 surface of the stone, and it has been heretofore found necessary at frequent intervals to clean the entire mixture of oil and grit from the surface of the stone in order that such particles all be removed and the stone permitted to function properly.

This cleaning process, has heretofore been done by wiping the stone free of oil by a cloth or similar fibrous article, which is objectionable in that it consumes the time of the opera tor unnecessarily. It also wastes the oil and tends to soil the hands of the operator. The invention contemplates the provision of a device comprising a receptacle having a wiping member somounted thereon as to provide a surface which can be rubbed over the stone in a manner to remove all of the metallic particles and leave a film of oil on the stone for further grinding operations. The wiping member is preferably constructed of cork or similar material which yields under pressure and enters the small interstices of the stone, thereby removing all of themetallic particles from the stone, which cannot be done by the use of a cloth.

An aperture in the Wiping member is filled with felt or similar material easily saturated by oil, which will be retained by the 'felt for a relatively long time. The felt leaves a film of oil on the surface of the stone and the invention further contemplates the provision of a chamber for oil so connected with the wiping member that a fresh supply of oil can be delivered to the felt portion of the wiping member at any time it may be necessary by operating a thrust valve or the like. The metallic particles can be easily removed from the wiping member by the use of a cloth or other similar article when such removal is found necessary. v

An ob'ect of the. invention is to provide a novel device operable to clean oil stones and which is effective, not only to thoroughly clean the stone of all metallic particles, but at the same time will leave a film of oil on the 7 stone.

Another object of the invention is to provide a device of the kind described, which is simple, compact, convenient, durable, reliable, efiicient and satisfactory for its intended purpose.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end, my inventionconsists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawing, wherein like reference characters indicate like or corresponding parts,

Fig. 1 is a vertical sectional view through one embodiment of the invention; Fig. 2 is a bottom plan view of the device shown in Fig. 1; and i Fig. 3 is a bottom plan view of" another embodiment of the invention.

Referring now more particularly to the drawing, the numeral 10 generally designates a cleaning device embodying the principles of my invention and comprising a cylindrical container 11 from which projects a wiping member 12. The member 12 is preferably constructed to fit closely within the container 11, with its upper end portion bearing against a Wall 14.

The container 11 forms a handle by means of which the member 12 is rubbed over the surface of the stone to be treated. I preferably construct the member 12 of cork which when moved under pressure over the surface of the stone will enter the fine interstices of the stone and cause the particles of metal contained therein to be imbedded in the cork, thereby effectively removing all of such metallic particles. Inasmuch as cork is substantially a non-absorbent of oil, some of the oil already on the surface of the stone will remain to form a film suflicient, in most cases, for furthergrinding operations. In order to insure that a sufficient supply of oil remain upon the stone after the grinding operation just described, I have provided an aperture centrally of the member 12 in which is wedged a member 13, constructed of felt. The member 13is preferably kept sufficiently saturated with oil so that, as the member 12 is moved over the surface of the stone, such additional oil as may be necessary will be simultaneously spread over the stone and form a film.

In the preferred embodiment of my invention the container 11 is so constructed as to provide a chamber 15 which can be filled with oil. While the device functions efficiently as a cleaner of oil stones in the manner above described, without the provision of such a chamber, I prefer to provide the same for convenience. IVhen the container 11 is utilized as a chamber for oil, the Wall 14 functions as a bottom of the container and a wall 8 as the top of the container, such walls being constructed so as to be fluid tight and retain the supply of oil 9. A screw plug 23 is removable for replenishing the oil supply in the container 11.

WVhen the oil in the felt 13 needs replenishin g this is accomplished by the operator pushing down on a plunger rod 16, on the lower end of which is a head 18. The upper edge of the head 18 is tapered to fit a tapered valve seat 17 formed in the wall 14, thereby permitting the head to be pushed downwardly into the felt and permitting a limited supply of oil to run from the reservoir 15 around the head 18 where it is absorbed by the felt. A knob 20 is mounted on the upper projecting end of the rod 16 for ease in manipulating the valve. A compression spring 19 is positioned between the head 20 and the top wall 8 to hold the valve 18 seated. A neck member 21 provides a housing for the spring 19. The upper end of "the member 21 provides a stop limiting the inward movement of the plunger rod 16. It is obvious that any desired degree of saturation of the felt 13 can be obtained by manipulating the valve. This manipulation can, if desired, be accomplished while the device is being rubbed over the stone.

In Fig. 3 I have shown a bottom plan view of an alternative embodiment of the invention comprising a container 22 having a wip ing member 23 similar to the member 12 shown in Fig. 1. A body of felt 24 is mounted in a central aperture in the wiping mem-- ber 23 in the same way as the felt 13 is mounted in the member 12. The alternative embodiment differs from the embodiment shown in Figs. 1 and 2 only in its shape, it being made rectangular and elongated. Likewise the container 22 is suitable, if desired, to provide a reservoir for a supply of oil.

IVhile I have shown a cylindrical construction and a rectangular construction, it is obvione that the container and Wiping member may be made of any other desired shape.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein described and shown, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. A device for forming a film of oil on the surface of an oil stone'and for the removal of grit therefrom comprising an oil receptacle, a cork member projecting from the receptacle and in which grit particles are adapted to be embedded upon rubbing the cork over the surface of the stone, said cork member having an aperture extending there through, felt or similar oil absorbing and dispensing material positioned in the aperture at the projecting end of the cork member and means operable to saturate said absorbing material by delivery of oil tothe inner portion thereof.

2. A device for forming a film of oil on the surface of an oil stone and for the removal of grit therefrom comprising an oil receptacle, a cork member projecting from the receptacle and in which grit particles are adapted to be embedded by rubbing the cork over the surface of the stone, said cork member having its projecting end terminating in a plane surface and having an aperture extending therethrough and terminating in said surface, felt or similar oil absorbing and dispensing material positioned in said aperture and providing a surface substantially coincident with said plane surface,

and means operable to saturate said absorbing material by delivery of oil to the inner portion thereof.

3. A device for forming a film of oil upon the surface of an oil stone and for the removal of grit from the stone, said device com- 7 end of said cork member being adapted for removal of grit particles when moved under pressure over the surface of the stone, felt or similar oil absorbing and dispensing material providing a filler for the cork member and means operable to saturate said absorbing material by delivery of oil from the cy1 inder to said absorbing material.

In Witness whereof, I hereunto subscribe my name this 31st day of October A. D., 1929.
